potted calibrachoa wilting - Knowledgebase Question

I have two potted calibrachoa callie plants (approx 4 months old) that are not flowering anymore and the leaves look a lighter sickly green. I repotted one and moved both plants from a hot full sun (morning to evening) location to a late afternoon sun location. I have fertilized once a week with all purpose fertilizer 12-5-5 and once with a fish emulsion. They are watered each day now that it is very hot here in June. Both are performing about the same and are not bouncing back. Any advice?

It sounds as though you are doing everything right! Calibrachoa are heavy feeders and like moist but not soggy wet soils. Keeping plants too wet can lead to root rot diseases. It is important to allow the top of the soil to dry before watering again. If your plant is wilting even though the soil is still damp you likely have a root rot problem. You might want to unpot one of the plants and check the root system, or you might want to simply cut the plant back to encourage healthy new growth. While not usually bothered by insects, an infestation of aphids or whiteflies can cause the leaves to take on a sickly green look. Inspect the underside of the leaves for pests (use insecticidal soap if you find them). Hope this information helps you determine the cause!
